Wait, there's people that don't have Prime?!
[Waves Hand] No, I don't. I don't order enough via Amazon to justify it. I purchase most things at brick and mortar because A) I like to hold in my hands and see what it is, because I hate having to pay for shipping both ways, and B) I hate paying shipping. Yes, I know it's built into the price at the B&M stores, but normally is a much smaller percentage of the cost then a one off sent UPS.
I will order books, simply because well they are books. Not some gizmo that may or may not be the right size, shape, color, voltage, etc. that I will have to send back.
